New Inventions. APPARATUS FOR MAINTAINING ARTIFICIAL RESPIRATION. THE appliance represented in the accompanying illustrations is intended principally for keeping up artificial respiration and has been devised by Dr. Rudolf Eisenmenger of Piski in Hungary. It consists essentially of a relatively high rigid dome of such a length as to extend from the upper part of the sternum to nearly the pubic region. It is attached to the patient by straps which completely encircle the body, and in order that the junction may be air-tight it has indiarubber packing along the lower side of the margin and, moreover, has flexible lateral flaps which reach almost to the patient’s spine. In Fig. 1 the dome and the indiarubber packing are shown in section, while the straps and the borders of the flaps are marked by dotted lines. On the summit of the dome there is a short tube giving access to the interior and connected to a long flexible tube which leads to a pair of bellows lying on the floor, as shown in Fig. 2. When the air within the dome is exhausted by the bellows the abdominal wall rises and air is drawn into the lungs ; on the other hand, the forcing of air into the dome by the bellows causes the lungs to be emptied. Evidently an effect will also be produced on the flow of blood to or from the heart. Dr. Eisenmenger says that the apparatus can be used not only for the treatment of persons suffering from asphyxia but also for the performIt is easily ance of abdominal massage. applied and is portable enough to be carried in a hand-bag, the total weight being from 20 to 30 pounds. pressure within the vessel.
